Question

Suppose that the growth rate of children looks like a straight ine the height of a child is months, 28 months, 32 months, and 36 months. If vou use the regression obtained from these ages of the child at 21 years, you might find that the predicted height is 20 feet. What is wrong process used? Chapter 4 Homework-Katrina Perkins with the prediction and the Choose the correct answer below. O A. The coefficient of determination is too low for the observed data. That is, the regression lne 0 B. Growt for the observed data does not fit well. One should not make predictions under these circumstances. h rates that are several standard deviations above the mean tend to be replaced by lower growth rates closer to the mean as people get older. This process is known as C. Growth rates slow as people get older. One should not extrapolate. That is, one should not D. At least one influential point caused the linear regression to be biased. It would be more regression toward the mean. One should not make predictions under these circumstances. predict outside the range of the data. appropriate to predict height after each influential point has been removed. the larger coefficient of determination is more strongly correlated. Which of the values shows a stronger correlation? Choose the correct answer below O A. A correlation of +0.1 gives a larger coefficient of determination and shows a stronger Does a correlation of -0.4 or +0.1 give a larger coefficient of determination? We say that the linear relationship that h B. A correlation of-04 gives a larger coefficient of determination, while a correlation of + 0.1 ° C. A correlation of-04 gives a larger coefficient of determination and shows a stronger OD. A correlation of +0.1 gives a larger coefficient of determination, while a correlation of -0.4 correlation shows a stronger correlation. correlation. shows a stronger correlation.

Explanation / Answer

Solution:

3) C. Growth rates slow as people get older. One should not extrapolate. That is, one should not predict outside the range of the data.

4) A. A correlation of + 0.1 gives a larger coefficient of determination and shows a stronger correlation.
